Determine if f could be a linear function
x 0 1 2 3 4
f(x) 3 5 7 11 15
is this a linear function
and then...
2x  6y = 12
3x9y = 27
What is the solution of the system of equations? A) no solution B) a point C) infinitely many solutions
Is the system consistent or inconsistent
Are the equations dependent or independent...
Thank you so much if you could help me out

1) no it is not linear.
2) The lines in the equations are parallel.
They are dependent, consistent, no solution. 
Juan solved the system of linear equations 8x3y=1 and 5x+2y=1
